The present invention relates to a liquid phase process for producing indium oxide-containing layers from nonaqueous solution, in which an anhydrous composition containing at least one indium halogen alkoxide of the generic formula InX(OR)where R=alkyl radical and/or alkoxyalkyl radical and X=F, Cl, Br or I and at least one solvent or dispersion medium is, in the sequence of points a) to d), in anhydrous atmosphere, a) applied to the substrate, b) the composition applied to the substrate is irradiated with electromagnetic radiation of wavelength &#x2266;360 nm and c) optionally dried, and then d) converted thermally to an indium oxide-containing layer, to the layers producible by the process and to the use thereof.

Process for producing indium oxide-containing layers, indium oxide-containing layers produced by the process and use thereof

The present invention relates to white-emitting copolymers which are obtained by a combination of blue-, green- and red-emitting repeating units. The copolymers of the invention display better film formation and an improved efficiency when used in polymeric organic light-emitting diodes compared to materials according to the prior art.

White-emitting copolymers, representation, and use thereof

Solutions comprising: (i) at least one organic semiconductor, (ii) at least one organic solvent A having a boiling point, and (iii) at least one organic solvent B having a boiling point; wherein the at least one organic semiconductor comprises at least one high molecular weight component, wherein the at least one organic solvent A is a good solvent for the at least one organic semiconductor, wherein the at least one organic solvent B is a poor solvent for the at least one organic semiconductor; and wherein the boiling point of the at least one solvent A is greater than the boiling point of the at least one solvent B; and the use of such solutions in processes for forming organic semiconductor layers on substrates and devices formed by such processes.
